Time needed to completely recharge a battery depends on the battery’s electrical capacity and present state of charge. Battery electrical reserve (RC rating) is given in minutes, and is needed when estimating recharge time.

Most batteries have a label attached showing the battery’s type and/or reserve capacity rating. If this information is not found on the battery, use the above chart to determine reserve capacity (RC) rating.

PN=17

Controls and Operation

Estimating Battery Recharge Time

1.Use table to determine time needed to completely recharge battery based on battery type, present state of charge, and charging rate (amps).

2.If recharge time cannot be estimated from the table,

calculate recharge time using the following formula: Recharge capacity (minutes) x 0.6 x 1.25 charge rate (amps) = approximate hours needed to recharge a totally discharged battery.

EXAMPLE:

80 x 0.6 x 1.25 10 = 6 hours

NOTE: Example uses an 80 minute reserve capacity battery and 10 amp charge rate.

When battery is not totally discharged, adjust charge time estimate using % DISCHARGED figure for calculation.

EXAMPLE:

6 hours x 0.75 = 4.5 hours

NOTE: Example shows adjusted time when battery is 25% charged (75% discharged). If battery was 75% charged, discharged figure of 0.25 would be used in adjusted calculation to arrive at 1.5 hours.

Controls and Operation

Activating and Charging a Dry Battery

Listed below are six steps to activate a dry-charged battery.

1.Remember Safety. Always wear protective glasses, gloves, and clothing when handling batteries and sulfuric acid electrolyte.

2.Prepare the Battery. Remove vents and date code

punch outs. If the battery or electrolyte is below 60°F, activation will be slower.

3.Add Electrolyte. Fill each cell with electrolyte until the level just touches the bottom of the “split vent” at the bottom of the vent well. Do not over fill by covering the split. If the split is covered, the gases created during charging will not escape properly, and will cause increased splashing and acid loss. Under filling can reduce the performance and life of the battery.

4.Let the Battery Absorb the Acid. It takes time for the battery plates and separators to absorb the acid. A 15 to 30 minute stand time before charging is recommended. Gentle rocking of the battery will help dislodge trapped air bubbles.

5.Charge the Battery. Charge the activated battery to ensure that it starts its life at 100% state-of-charge. Activated batteries should be charged at no more than 1% of CCA for 30 minutes, and up to 6 hours in cases of extremely high humidity storage. For example, a 625 CCA battery should be charged at 6 amps. Reduce the charging rate if excessive gassing occurs.

Charging is recommended when:

a.The voltage of the activated battery is below 12.4 volts, even after 15 minutes stand time.

b.The battery will not be installed within the next 30 days.

c.The outside temperature is below 32°F.

d.The battery has been in storage for more than two years.

6.Top off the Electrolyte Level. Add electrolyte as required to bring the level back up to the bottom of the split vent in the bottom of the vent well. The acid level may have dropped due to absorption into the plates and separators. Replace the service vents.

Service hints for longer battery life:

Add only pure drinking water or distilled water to the battery after it is placed in service.

Disconnect the ground cable when the vehicle is stored for more than three months. Cleaning the battery top, adding water, and charging the battery before vehicle storage will reduce discharge and sulfation battery failures.

Specific gravity is the best indicator of battery state-of charge.
